Man here. I was once a mandatory reporter so i absolutely know some rapists. Some of the cases involved men (or women) i knew.
I do want to acknowledge that women are disproportionately the victims of sexual violence and rape, but if i could id just mention that victims of sexual violence and rape can be any gender, and the rapists can be any gender as well. I mention that since the sign kind of assumes that men won't be victims themselves or that they wouldnt tell their friends like women.
I hope that pool doesn't become a piece of posthumous art
